AUTOMATIC PHONOGRAPH STOP AND START DEVICE.

Application filed March 31, 1921. Serial No. 457,413.:

To all whom it may concern:

Be it known that I, EVERETT HUoKEL BICKLEY, a citizen of the United States, residing at Upper Darby, county of Delaware, State of Pennsylvania, have invented a certain new and useful Improvement in Automatic Phonograph Stop and Start Devices, of which the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings.

The object of the invention is to provide a very simple and cheap device for operating the brake of a phonograph from movements and positions of the tone arm.

My invention provides a simple, compact, cheaply manufactured device which may be installed on practically any make of phonograph successfully provided the tone arm is driven from the record, and the record groove spiral ends in a closed ring or circle. When it is desired to start the phonograph using this device, the tone arm is swung to the extreme outer position momentarily, thus releasing the brake. When the tone arm has been carried by the spiral record groove to the inner circle, my device automatically releases the brake which stops the machine.

My invention is hereinafter more fully explained, and its characteristics set out in the claims.

In the drawings, Figure 1 is a plan view of my device, showing it applied to a phonograph, certain parts of the turn-table and tone arm being broken away to show the one method of application of my invention. Fig. 2 is a perspective view to a larger scale of the wheel and finger disc. Fig. 3 is a sectional elevation to larger scale of a finger, friction lever, and brake trip arm, with the plate, showing relative positions when operating. Fig. 4 is an enlarged view of an alternate construction of the fingers f Referring to the parts shown in the drawings, a is a worm which is mounted on and driven by the center spindle Z) of the phonograph. 0 is the turn-table of the phonograph which is also mounted normally on the spindle b above the worm a. The sound record 0 is shown on the turn-table c. A worm-wheel cl is mounted rigidly on the shaft 6 and meshes with the worm a.

A finger-disc f is also mounted rigidly on the shaft 6. The worm-wheel, shaft and finger-disc is mounted on bent up lugs on the plate 9 so that it is free to rotate about the center of the shaft 6, but is restrained from moving lengthwise of the shaft 6. The friction lever H having a bifurcated end h and a pin extending downwards at h is attached to the lever m by the friction joint is. This joint permits the lever H to lag behind the motion of the lever we when restrained by the sides g and g of the plate 9 or the action of the fingers f. The lever m is mounted rigidly to the tone arm and moves with it. The tone arm n moves to the outer position n carrying the lever m with it. The

pin'at it now engages the arm 9 on the la ver' Q and the lever Q, moving about its fulcrum t stretches the spring rand removes the pressure between the friction pad 8 and the edge of the turn-table 0 The prong g meanwhile latches behind the side g 'holding the brake in the inoperative position. The tone arm is now swung in, and the selection on the record is played.

The friction lever H meanwhile rubs on theside g and approaches the rotating finger disc f After a portion of the record has been played the bifurcated end of the friction lever H engages with the fingers f and is pushed away from the side 9 a certain distance by each of the fingers 7. This.

motion taking place in a horizontal plane as shown in Fig. 3 by the dotted lines. The movement of the tone arm n and the lever m carry the friction lever H in theopposite direction to this push so that the rotating fingers 7 will strike the slot h in the friction lever H as long as the tone arm is fed inwards. When the end of the record is reached, and the motion of the tone arm inward ceases, the lever H no longer moves inward so that the fingers enter the slot h, but

the finger f strikes the top of the friction lever H driving it downward against the lever Q, which is unlatched thereby at g from g and the spring r applies the brake s,

at c stopping the turn-table 0, The friction joint 7:; is weakly adjusted so that no load is put on the tone arm to speak of, and .the side 9 is provided to guide the friction lever H when thetone arm n swings back to the a position. The plate 9 is suitably attached to the top of the phonograph by screws as shown or otherwise. If the stop is to be used in connection with records that are not a perfect spiral, or records that are,

of the turn-table is required from the time the leading edge of the finger f clears the top surface of the friction lever H until the trailing edge of the finger f clears the bottom surface of the friction lever H. The finger f is also made to very closely fit the slot in the lever H on the trailing edge. This construction will operate perfectly on very defective records. Not limiting myself to the exact construction shown, as it is possible to obtain the same result by incorporating the friction joint in the tone-arm, and use a manually operated brake release, or it may be released by a cam on the tone arm, etc.
